A can of PondMAX Black Waterfall Foam holds roughly 12.3L (750in3) of expanded foam; this makes a bead of foam 1.27cm (1/2in) diameter about 165cm (575ft) long. Cured foam resists solvents, water and weathering.
Foam which is exposed to direct sunlight can be painted to protect against gradual decomposition or discolouring.
PondMAX Black Waterfall Foam expands and fills voids between rocks and liner, so as to divert water in desired direction. It simplifies waterfall construction and can be easier to use and apply than mortar.
The foam will not crack or breakdown in freezing temperatures. The black colour of the foam will blend into the waterfall setting and maintain its durability. The PondMAX Black Waterfall Foam will not harsh fish or other aquatic life. It cures within 40 minutes and excess foam can be easily removed if necessary, once it's dried.
